class subtraction{
	private:
		int first;
		int second;
	public:
		subtraction(){
			first  = 0;
			second  = 0 ;
		}
		void get_numbers(int a, int b){
			cout<<"Enter the first number:\n";
			cin>>a;
			cout<<"Enter the second number:\n";
			cin>>b;
			first = a;
			second = b;
			
			
		}
		void display(){
			cout<<"The difference is:  "<<first  -  second<<endl;
		}
};


int main(){
	int a,  b;
	subtraction c;
	c.get_numbers(a,b);
	c.display();
}
